中国工业产业利润差异及其决定因素——2000～2004年中国工业企业的经验证据

Difference of Profit and the Determinants in China Industry——Empirical Analysis of Chinese Industrial Enterprises from 2000 to 2004

利用2000～2004年我国规模以上工业企业大样本数据，全面测度了中国工业领域各行业的利润水平及差异状况。结果表明，处于转轨时期的我国所表现出的行业利润分布和行业利润差异，即通常意义的市场结构变量，如集中度、企业规模等因素，由于与我国特有的所有制和股权因素等掺杂在一起而丧失了预期的显著效果。因此，在市场化转轨时期，政府人为的管制以及对待不同所有制企业的差别政策，是产生工业企业行业利润差异的重要原因。

Based on the data of China industry enterprises from 2000 to 2004, this paper measures the level and the difference of profits in all kinds of industries. The primary result shows that the profit distribution and the difference of profits in China industry bear unique characteristics during the transition period. Jointed with the factor of ownership structure, the traditional variahos of market structure, such as the coneentration degree of industry and the enterprise scale, have lost their expected impacts on the profits of enterprises. This paper concludes that during the period of Chinese mercerization and transition, government intervening and the discrimination between enterprises of different ownerships have been the important factors which affect the difference of profits of industrial enterprises.
